As film enthusiasts know, some of the greatest movie monsters of all time are based on the real-life animals walking, flying, and swimming around the planet. While there's no shortage of weird animals out there in nature, they become even weirder once you zoom in on specific body parts - like their mouths. These terrifying animal mouths might give you nightmares. The mouths of the anglerfish or payara bear an uncomfortable resemblance to the xenomorph from Alien, and the hagfish is like something straight out of an H.P. Lovecraft story.

But that's just the beginning of the terrors nature has to offer, at least as far as mandibles, tongues, and teeth go. This list just might make you second guess how cute penguins are, or your decision to adopt a pet tortoise. If you ever find yourself on land or in the water with one of these terrifying creatures, remember: don't look it straight in the mouth. You will freak out.
